I have a problem with my rangie going up hills
It has no power and I am pushing to get up to 40 km on a steep hill
Recently I changed the air and oil filters. The problem was there before I did the service.
Can anyone shed any light on this problem
Cheers Paul

Maf sensor. Disconnect it and go for a drive

Not sure what a maf sensor is, where would I find it to disconnect .
Cheers Paul.

Does it whistle at all under load? If so, check the small vacuum line between the inlet manifold and the turbo actuator plenum on the drivers side of the engine. Pull the hose off and stick your finger over it - if you have no suction, you will have no power as the vacuum is required to operate the VNT turbo. If you have vacuum there, check at the turbo for the same thing. The vacuum line gets brittle and cracks and this causes a slow decline in power until it won't go up hills anymore. It will still start fine and not throw any fault codes.

A MAF is a mass air flow sensor. it measures the volume of air going into the engine. when you disconnect it will go to default setting. It still wont have full power but will be driveable if the MAF has failed. It is a common failure. It's located near the air filter.

I had similar issue and it turned out to be injector harness. $130 for a new harness and about 40 mins later and issue was fixed. I hope yours is as simple!

With power loss, I always recommend checking the inline fuel pump, put ur head down infront of the L.H rear wheel (not while moving or in neutral) and if you can hear a whinning/buzzing sound, it most likely needs to be replaced along with the fuel filter.
it will come to the point where they can stop completely and be intermittently working.
I ended up replacing it twice, second time with a more common/cheaper/reliable bosche pump

There you go Brummy - that should keep you out of trouble for a while checking that lot - all can cause your symptoms and all of them are pretty common. :)

let us know who wins the jackpot or if we were all wrong. :D

some pics of the different engine bay parts/locations may help:D

We should start up a competition....:wasntme:

No, because I think your suggestion is the most likely... :D. It hasn't happened to mine.... Yet... But the turbo vac line has. Reading through FFRR the inline pump seems to be one of the most common failures... after the transmission.

[BRUMMY]

Yes Bacicat , you have nailed it, it does have a whistle.
I drove to the airport this morning with both windows down, on the level it is fine but any gradient and it's singing like a canary......ha ha......
I'm up in Singapore now, but will be back home on Thursday and work from your suggestions.
Cheers Paul

To me, a turbo diesel should whistle (within reason)? :confused: I know mine whistles like crazy and i have a boot load of power whenever I want it.
when the vacuum line is off, there was no noise at all on mine.

[Homestar]

Interesting - on mine, when the turbo has little or no vacuum it whistles like crazy - it does whistle under normal usage too, but much worse when it has had this issue.

I have just been through the same thing. Smash repairer pressure cleaned engine bay and damaged ABS Computer. They are denying that they had anything to do with it despite it working perfectly prior to going in for repair and insurance won't pay mor new module based on the fact that there is no hard evidence pointing to them being responsible! They are stating that as the vehicle is over 10 years old that it is wear and tear....not a happy camper!!!

When ours was hit, I insisted it was taken to a prestige repairer. The other persons insurance company complained bitterly about this and said I needed to get the, 3 quotes - I told them to shove it 'my car, your fault - my way' - which I got. The repair was better than new, and they treated the car well - the place was spotless - and my car was the cheapest in there by miles :D

The insurance company got a bill for over $8K for a new bumper (not second hand), 1 repaired panel and paint.

[Steinzy]

I should have done the same!
